Chapter 6 focuses on the properties of normal distribution. The chapter also describes how to calculate area under the standard normal distribution and find probabilities for a normally distributed variable by transforming it into a standard normal variable. In addition, the chapter describes the calculation of specific data values for given percentages by using the standard normal distribution.

Applying the Concepts

A normal distribution is a theoretical distribution used to describe many variables because the deviations from a normal distribution are small. Normal distributions may be useful for approximating binomial distribution.
